b) A vibrating tuning fork is held next to an adjustable open-closed tube. The frequency of the tuning fork is also the fundamental frequency of the tube at its shortest length. When the tube slowly increases its length, the fourth resonance is heard when the length is 76.1 cm. i. Draw the standing wave pattern for the fourth resonance (indicate what type of wave you use for the sketch). ii. significant figures] What is the frequency of the tuning fork? The air is 82.0 F.
